使用 Java 调用 SOAP Web 服务时如何修复不可读的 XML 响应

调用SOAP Web服务

我有一个要调用的SOAP Web服务，以下是我的代码:

private List<Guaranty> getGuarantyList(String nationalId, String centerBankCode) throws IOException{
        
        try {
            fixHttpsHandler();
        } catch (Exception ex) {
            System.out.println(ex.getMessage());
        }

        // Code to make a webservice HTTP request
        String responseString = "";
        String outputString = "";
        String wsEndPoint = "http://192.168.5.202/services/out.asmx";
        URL url = new URL(wsEndPoint);
        URLConnection connection = url.openConnection();
        HttpURLConnection httpConn = (HttpURLConnection) connection;
        ByteArrayOutputStream bout = new ByteArrayOutputStream();
        String xmlInput = "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:pos=\"http://postbank.ir/\">\r\n" + 
                "   <soapenv:Header>\r\n" + 
                "      <pos:PostbankAuth>\r\n" + 
                "         <!--Optional:-->\r\n" + 
                "         <pos:UserName>ebank</pos:UserName>\r\n" + 
                "         <!--Optional:-->\r\n" + 
                "         <pos:Password>qwer@123</pos:Password>\r\n" + 
                "      </pos:PostbankAuth>\r\n" + 
                "   </soapenv:Header>\r\n" + 
                "   <soapenv:Body>\r\n" + 
                "      <pos:getGuaranty>\r\n" + 
                "         <!--Optional:-->\r\n" + 
                "         <pos:nationalCode>" + nationalId + "</pos:nationalCode>\r\n" + 
                "         <!--Optional:-->\r\n" + 
                "         <pos:centerBankCode>" + centerBankCode + "</pos:centerBankCode>\r\n" + 
                "         <!--Optional:-->\r\n" + 
                "         <pos:length>10</pos:length>\r\n" + 
                "         <pos:offset>0</pos:offset>\r\n" + 
                "      </pos:getGuaranty>\r\n" + 
                "   </soapenv:Body>\r\n" + 
                "</soapenv:Envelope>";
        byte[] buffer = new byte[xmlInput.length()];
        buffer = xmlInput.getBytes();
        bout.write(buffer);
        byte[] b = bout.toByteArray();
        String SOAPAction = "http://postbank.ir/getGuaranty";
        httpConn.setRequestProperty("Accept-Encoding", "gzip,deflate");
        httpConn.setRequestProperty("Content-Type", "text/xml; charset=utf-8");
        httpConn.setRequestProperty("SOAPAction", SOAPAction);
        httpConn.setRequestProperty("Content-Length", String.valueOf(b.length));
        httpConn.setRequestProperty("Host", "192.168.5.202");
        httpConn.setRequestProperty("Connection", "Keep-Alive");
        httpConn.setRequestProperty("User-Agent", "Apache-HttpClient/4.5.5 (Java/16.0.1)");
        httpConn.setRequestMethod("POST");
        httpConn.setDoOutput(true);
        httpConn.setDoInput(true);
        OutputStream out = httpConn.getOutputStream();
        // Write the content of the request to the outputstream of the HTTP
        // Connection.
        out.write(b);
        out.close();
        // Ready with sending the request.
        // Read the response.

        InputStreamReader isr = new InputStreamReader(httpConn.getInputStream(), Charset.forName("UTF-8"));

        BufferedReader in = new BufferedReader(isr);
        // Write the SOAP message response to a String.
        while ((responseString = in.readLine()) != null) {
            outputString = outputString + responseString;
        }
            
        String formattedSOAPResponse = formatXML(outputString);
        return formattedSOAPResponse ;
        
    }

但我得到的是响应，而不是一个可读的XML:

这种方式适用于其他Web服务，但不适用于此Web服务.我在SOAP-UI中测试了Web服务，它工作正常…… 谢谢
